For the price, this product seems to be doing a pretty good job on my 90g tank that was overtaken by free-floating algae (aka green water). I bought the 24W model and I went from not being able to see into the tank at all into finally being able to see the back of the tank after about 4 days. It's still a recent purchase for me but I'm pleased with it so far.

I own two of the 2-bulb fixtures (a 78W and a 108W) and they don't come with fans so they can get pretty hot. With the 108W fixture, when the light come on it makes a popping sound for a while and then makes the same sounds again at lights off. Not sure what it is.

I don't recommend anyone use a single food source for their livestock. I include this product in a mixture of about 5 different flake foods, brine shrimp, plankton and bloodworms. All of the food is gone as soon as it enters the tank so I doubt the fish have any complaints.

It's easy to clean gravel with using the attachment but after switching to a planted tank with sand, I removed the attachment and use the hose for siphoning off of the sand when occasionally needed and used the attachment for a DIY CO2 reactor.

It might be a tad bit pricey but it's really a one-time investment. It's so easy to use and if they detach, it'll just float to the top so you don't need to reach in to retrieve it. I love also being able to go from one glass to the next without needing to moving it from inside the tank. Highly recommend.

I began using this sand when I switched over to a planted tank. I love the black sand because it contrasts well with the green plants and it really helps to make the fish pop. I don't even vacuum the poop off of the sand because it just blends right in and my plants eventually use it as fertilizer. Only complaint is I had to order it online and it could be a bit expensive.

This test kit is vital for keeping corals. The calcium test kit is a must for keeping hard corals. The phosphate and nitrate tests are important to monitor for keeping algae in check. Highly recommend to anyone who owns a reef tank.
